Input assistance device, input assisting method, and recording medium storing input assistance program

An input assisting method, comprising:

• storing a plurality of types of operations targeting a display object arranged in a shared screen shared by a plurality of terminal devices in operation storing unit;
• storing a history operation that is a performed operation targeting an arranged object that is the display object stored in display object storing unit and arranged in the shared screen, in order of performance of the history operation, and storing participating user identifiers that are identifiers of users of the plurality of terminal devices in an operation history storing unit;
• and
• deriving an operation probability being a probability that a target user who is a user of a target terminal device in the plurality of terminal devices performs next time a candidate operation being the operation stored in the operation storing unit, based on a target user identifier being an identifier of the target user, the history operation, and the participating user identifier.

A non-transitory computer-readable recording medium storing an input assistance program causing a computer to operate as:

• operation storing unit which stores a plurality of types of operations targeting a display object arranged in a shared screen shared by a plurality of terminal devices;
• operation history storing unit which stores a history operation that is a performed operation targeting an arranged object that is the display object stored in display object storing unit and arranged in the shared screen, in order of performance of the history operation, and for storing participating user identifiers that are identifiers of users of the plurality of terminal devices;
• and
• operation score deriving unit which derives an operation probability being a probability that a target user who is a user of a target terminal device in the plurality of terminal devices performs next time a candidate operation being the operation stored in the operation storing unit, based on a target user identifier being an identifier of the target user, the history operation, and the participating user identifier.
